             2005       2006                 2007   2008

     P2P, FR links give way to MPLS and MEN
     MPLS and MEN give L2 and L3 functionality
     ISDN and FR almost obsolete in current scenario
Trends : Ethernet—The “Next Utility”

Advantages : Ethernet as a Leased Line

• Dominates the LAN
   • Native interface
   • Plug-n-Play

• Ease of use
   • Widely available, well understood technology
   • Simplifies network operations to enterprises

• Cost Effectiveness
   • Widespread use of Ethernet interface
   • No CPE required
   • Purchase bandwidth only as and when needed
   • No need to add hardware for upgradation of bandwidth

• Flexibility
    • Bandwidth can be added in small increments as and when required
    • Single interface can connect to multiple services
         • Internet, VPN, Extranet supplier, Storage Provider
Why does Enterprises need Ethernet?

                  Provide “Carrier-Class” Data Service (Private Line) with
                                      Flexible Speeds
  2.5 Gbps
    Security Measures by Telecom Companies
   In MEN networks- traffic is carried on ‘system-configured’ Ethernet Virtual
    Circuits’- mapped between physical Ethernet ports of the originating and
    terminating MEN nodes. These VC/VLAN Ids are residing with the
    Management system and shall not be compromised.
   No user- whose access ports are not pre-configured as part of the EVC
    can access the network from any other MEN node/port.
   There are no „port-mirroring‟ or similar features that allow other users to
    monitor any specific traffic .
   Only specific ports used by the customer is active at any Node- other ports
    are de-active
   In case the traffic levels of any customer reaches/exceeds a threshold, then
    telcos can also dedicate a fibre pair for the customer- thus making the
    network absolutely secure.
    Reduction in Site Requirements

   Smaller Equipment
   Less Space Requirement
   Less Power Requirements

Metro Ethernet Network in HUL
    Introduced by Reliance Communications in 2005, first link
     commissioned between Bangalore and Mumbai (5Mb).
    HUL saw great cost benefits in terms of Device requirements
     and bandwidth upgrades.
    Link stability and ease of use has improved acceptability
     within HUL, all major offices are connected on MEN only.
    MEN so far very stable and gives better uptimes.
    HUL uses Bandwidth on Demand Extensively.

    HUL DC-DR replication runs on another flavor of ME called
     EoSDH on large capacities.
    Currently HUL has 15+ ME links, with aggregated capacities
     of 64Mb+ on MPLS, 125Mb+ on ME P2P, 45Mb+ on Internet.
    Evaluating VPLS solution on ME for Intra city connectivity
